TacoBill -> Speed of Sound (SOS) switch plate install (w/pics & vid) (7/17/2007 7:03:34 AM)
|
I made the decision to swap out my Shaker 500 head unit with the latest Alpine DVD unit and also add a rear camera and a shift light. I wanted to be able to switch on/off the TR-7 video bypass, rear camera, and the Raptor shift light. I could have opted for some cheap toggles (which would’ve looked tacky), but instead found an awesome looking switch plate made by Speed of Sound.
I ordered the 4 toggle switch layout with a 2 1/16” gauge opening for no particular reason other than I really like this layout. I chose an Auto Meter Ultra-Lite II Voltmeter gauge and it fit the bill perfectly.
The SOS switch plate comes pre-wired with leads for easy connections. According to SOS, the switches and wires are sufficient for low-amperage (up to 15 amps maximum) applications. Any high-amperage applications will require heavier gauge wiring and relays.
Each switch has 3 prongs and typically get wired this way…
BLACK – Connected to common vehicle ground (used to illuminate the switch’s LED)
RED (center) – Connected to either a constant 12V or switched 12V depending on your application
RED (opposite end on black) – Connected to accessory circuit 12V in (In my case, Positive lead on Raptor, rear camera, and voltmeter)
Note: The Negative leads off the accessories get grounded to a common ground, NOT TO THE NEGATIVE LEAD ON THE SWITCH!

A Dremel was used to make a small hole in the bottom of the rear cup holder (after removal of the short cup base; pulls right out) to feed all the wires up to the switch panel.

The wiring can get a bit confusing so it may be a good idea to tape off each accessory and label it. Key here is to take your time and do one wire at a time.
Tip: To make soldering, heat shrinking, or wire twisting task easier, disconnect the spade terminal from the switch.

Each switch controls the Raptor shift light, rear camera, DVD video bypass, and the voltmeter.
Here are some pics and one video of the completed project.
Note: The reason why you don’t see the ‘DVD’ LED switch illuminated is because the video bypass circuit that the switch interrupts is less than 12V (or is momentary). I removed the Negative terminal off this switch since it isn’t needed.
